The EAS® -compact is a positive-locking, detenting or disengaging safety clutch based on the ball-recess principle. The clutch protects the driveline against impermissibly high torque surges which can occur due to unforeseen blockages.

If the set torque is exceeded (overload condition), the clutch disengages and a residual torque of approx. 5 - max. 15 % of the set torque is applied. After removal of the overload, the clutch automatically engages in the detent position.
